This paper proposes a High Dynamic Range (HDR) system with low computation complexity based on inexpensive electronic devices. It utilizes advanced hardware structure with CMOS sensors that can generate multiple frames consisting of long and short exposures. In addition, the interval time between long and short frames can be set to a few msec or even less. Existing HDR recovering and compression techniques are used in the proposed system. Both the regular mode and the HDR mode share the same image processor and keep the same sensor characteristics. It exhibits minimum impact to the image processing unit while demonstrates excellent HDR performance.
